Abstract

Technologies for reducing event notifications in telematics systems includes a telematics server, a telematics device located in a vehicle, and a notification device. The telematics server receives telematics data from the telematics device and analyzes the telematics data based on an event model to determine whether an unexpected event has occurred. The event model includes a plurality of rules that define expected events related to the vehicle based on historical telematics data. The server generates a notification in response to a determination that the unexpected event has occurred and transmits the notification to the notification device, which may generate a notification to an end user. The event model may be generated and updated by the telematics server using an unsupervised and/or supervised machine learning algorithm based on the telematics data.

Description

FIELD OF THE DISCLOSURE

The present disclosure relates generally to telematics and associated telematics devices and, more particularly, to telematics systems configured for providing notifications to end users.

BACKGROUND

Telematics involves the integrated use of telecommunications and informatics, particularly for application in vehicles. Telematics functionality may include, but is not limited to, recording vehicle information, emergency warning systems, navigation functionality, safety warnings, and automated driving assistance. Vehicle telematics devices may process and transmit telematics data and other messages generated by a vehicle and connected devices. For example, the telematics data may be produced by sensors, controllers, and/or other peripheral devices located on the vehicle and/or within the telematics device itself.

In some telematics systems, the vehicle telematics devices may transmit the locally collected telematics data to a telematics server. In typical telematics systems, especially those related to fleet operations, Transportation & Logistics (T&L), and Connected Vehicles, the telematics server may continually or periodically transmit notifications to an end user of the system, such as a fleet manager, a driver of the associated vehicle, or a customer of the service (e.g., a parent of a monitored child) based on the received telematics data to keep the end user informed and the telematics device up-to-date. However, such reoccurring notifications can consume a large amount of bandwidth and become excessive and unmanageable for the end user.

SUMMARY

According to an aspect of the present disclosure, a telematics server for providing notifications to a telematics device of a vehicle may include an event model, a device interface, and a notification manager. The event model may include a plurality of rules that each define an expected event based on historical telematics data of the vehicle. The device interface may be configured to receive telematics data from the telematics device, and the telematics data may define one or more characteristics of the vehicle. The notification manager may be configured to analyze the telematics data using the event model to determine whether an unexpected event has occurred and, in response to a determination that the unexpected event has occurred, generate a notification. The device interface may be further configured to transmit the notification to a notification device.

In some embodiments, the notification manager may be configured to update the event model based on the telematics data received from the telematics device or based on feedback received from the notification device using a machine learning engine. Additionally, in some embodiments, the notification may instruct the notification device to generate an alert.

In such embodiments, the sequential-based rule may define an expected event related to the vehicle given an occurrence of a prior event related to the vehicle. Additionally, in some embodiments, to analyze the telematics data may include to analyze the telematics data based on a relational-based rule of the event model. In such embodiments, the relational-based rule may define an expected characteristic of the vehicle given a state of another characteristic of the vehicle.

The telematics data may define one or more characteristics of the vehicle, and the event model may include a plurality of rules that each define an expected event based on historical telematics data.

In such embodiments, the method may further include updating, by the telematics server, the event model based on the telematics data received from the telematics device or based on feedback received from the notification device using a machine learning engine.

Referring now to FIG. 1 , an illustrative telematics system 100 for providing notifications to a telematics device includes a telematics server 102, a telematics device 104 installed in a vehicle 106, and a notification device 108. Each of the telematics device 104 and the notification device 108 are in communication with the telematics server 102 over a network 110. In use, as described in more detail below, the telematics server 102 receives telematics data from the telematics device 104 via the network 110, analyzes the telematics data based on an event model (e.g., a machine learning model) to determine whether an unexpected event has occurred as indicated by the telematics data, and transmits a notification to the notification device 108 via the network 110 if the occurrence of an unexpected event has been detected. As such, the overall bandwidth of notifications between the telematics server 102 and the notification device 108 may be reduced by transmitting only notifications regarding unexpected events (e.g., the vehicle 106 is in an unexpected location, the vehicle 106 has failed to arrive at a location at an expected time, the vehicle 106 is traveling an unexpected rate of speed, etc.). In some embodiments as discussed in more detail below, the event model may be constructed, updated, and/or maintained using a machine learning algorithm based on received telematics data such that the expected behavior of the vehicle 106 can be more accurately determined over time.

The notification may be embodied as any type of notification. For example, in some embodiments, the notification may include instructions for the notification device 110. For example, the notification may instruct the notification device 110 to generate an alert. Additionally or alternatively, the notification may be configured to provide information to the user of the notification device 110 (e.g., information regarding the determined unexpected event), which the notification device 110 may present to the user via the output device 178.

The notification manager 212 is configured to analyze the telematics data received from the telematics device 104 and determine whether an unexpected event has occurred based on the event model 222. That is, the notification manager 212 compares the received telematics data to one or more rules included in or otherwise defined by the event model 222 to determine whether the telematics data define an unexpected (e.g., abnormal) event based on historical telematics data. As discussed in more detail below, the event model 222 includes a number of rules which define an expected operational condition or characteristic of the vehicle 106 (i.e., expected telematics data). For example, the event model 222 may include temporal-based rules, location-based rules, historical based rules, sequential-based rules, relational-based rules, and/or other types of rules that define expected telematics data. In some embodiments, for example, the event model 222 may include a rule that indicates the vehicle 106 is typically at a particular location at a particular time. In such embodiment, if the received telematics data does not indicate that the vehicle 106 is located at the expected location, the notification manager 212 may determine that an unexpected event has occurred and generate an associated notification for transmission to the notification device 108. Other operational aspects of the vehicle 106 may also be monitored for unexpected events such as sudden changes in the driving pattern of the vehicle 106 such as excessive acceleration, excessive declaration, and/or lane departures.

The model manager 214 is configured to construct, maintain, and update the event model 222 based on newly received telematics data and, in some embodiments, feedback from the user of the notification device(s) 108. As discussed above, the event model 222 includes a number of rules that define an expected operational condition or characteristic of the vehicle 106 (i.e., expected telematics data) based on historical telematics data. The model manager 214 may initially define those rules during an initial training period during which telematics data is monitored using an unsupervised machine learning algorithm (e.g., to identify commonality in the telematics data). Over time, the model manager 214 is configured to continually update the event model 222 such that the rules of the event model 222 define the presently expected operational conditions and/or characteristics of the vehicle 106. To do so, in some embodiments, the model manager 214 may include a machine learning engine 216 configured to monitor the received telematics data overtime and update the event model 222 based on “learned” operational conditions and/or characteristics of the vehicle 106. In this way, the event model 222 can be maintained in a current form without manual updating. Additionally, the user of the notification device 108 may provide feedback based on generated notifications, which the model manager 214 may use to further update the event model 222 using a type of supervised machine learning algorithm.

The data manager 218 is configured to manage the telematics data received from the various telematics devices 104. For example, the data manager 218 stores the received telematics data in the telematics database 220. To do so, the data manager 218 may utilize any suitable storage paradigm.

Still referring to FIG. 2 , in the illustrative embodiment, the telematics device 104 establishes an environment 204 during operation. The illustrative environment 204 includes a data collection manager 230, a data transmission manager 232, a server interface 234, an alert manager 236 and various data sets including a local telematics database 240 and, in some embodiments, a transmission ruleset 242. Similar to environment 202, the various components of the environment 204 may be embodied as hardware, firmware, software, or a combination thereof. As such, in some embodiments, one or more of the components of the environment 204 may be embodied as circuitry or a collection of electrical devices (e.g., data collection manager circuitry 230, data transmission manager circuitry 232, server interface circuitry 234, and/or alert manager circuitry 236). It should be appreciated that, in such embodiments, one or more of those components may form a portion of the processor 142, the I/O subsystem 146, and/or other components of the telematics device 104.

The data collection manager 230 is configured to collect telematics data from various controllers 162 and/or sensors 164 of the vehicle 106. As discussed above, in some embodiments, the telematics device 104 may receive such telematics data via the vehicle bus 160 and bus connector 154. Additionally, in embodiments in which the telematics device 104 includes the local sensors 156, the data collection manager 230 may also receive or collect telematics data from the local sensors 156. In doing so, the data collection manager 230 may utilize any suitable data collection scheme including, for example, data pushes, data pulls, and/or data doorbells. As such, the telematics data may be sampled or received according to any suitable data acquisition scheme.

The data transmission manager 232 is configured to manage the transmission of the telematics data from the telematics device 104 to the telematics server 102. To do so, the data transmission manager 232 may use any suitable transmission schedule to transfer the telematics data to the telematics server 102. For example, in some embodiments, the data transmission manager 232 may be transmit the telematics data as it is received from the various controllers 162, sensors 164, and/or sensors 156. In other embodiments, the data transmission manager 232 may transmit the telematics data based on a schedule set forth in the transmission ruleset 242. That is, the transmission ruleset 242 may define a set of rules that dictate a frequency at which the telematics data should be transmitted. For example, the transmission ruleset 242 may define a batch timing (e.g., every 30 seconds) at which all collected telematics data is to be transmitted, a data threshold amount at which the collected telematics data is to be transmitted, and/or other conditions under which the telematics data should be transmitted to the telematics server 102. In some embodiments, the transmission rules may be based on the type of telematics data (e.g., important telematics data may be transmitted at a higher frequency than non-important telematics data).

The server interface 234 is configured to establish communications with the telematics server 102. In use, the server interface 234 transmits the telematics data when instructed to do so by the data transmission manager 232. Additionally, in some embodiments (e.g., those embodiments in which the telematics device 104 includes or is embodied as the notification device 108), the server interface 234 may receive notifications transmitted by the telematics server 102 (as well as any other data), based on the transmitted telematics data.

In embodiments in which the telematics device 104 includes or is embodied as the notification device 108, the alert manager 236 is configured to manage the notifications received from the telematics server 102. In embodiments in which the notification includes instructions, the alert manager 236 is configured to execute the instructions of the received notification. For example, the alert manager 236 may activate an alert device of the telematics device 104 and/or vehicle 106 based on the notification. Additionally or alternatively, in embodiments in which the notification includes information to be provided to the driver, the alert manager 236 is configured to present the information to the driver via the output device 152 (e.g., via a display screen or speaker).

In some embodiments, the alert manager 236 may include a local event model 238. The local event model 238 may be a copy of the event model 222, or a subset thereof, and is received by the telematics device 104 from the telematics server 102. In such embodiments, the alert manager 236 may be further configured to operate in a manner similar to the notification manager 212 of the telematics server 102. That is, the alert manager 236 may locally analyze the telematics data to determine whether an unexpected event has occurred based on the local event model 238 similar to the functionality of the notification manager 212 discussed above.

Continuing reference to FIG. 2 , in the illustrative embodiment, the notification device 108 establishes an environment 206 during operation. The illustrative environment 206 includes a communication manager 250 and an alert manager 252. Similar to environments 202 and 204, the various components of the environment 206 may be embodied as hardware, firmware, software, or a combination thereof. As such, in some embodiments, one or more of the components of the environment 206 may be embodied as circuitry or a collection of electrical devices (e.g., communication manager circuitry 250 and/or notification manager circuitry 252). It should be appreciated that, in such embodiments, one or more of those components may form a portion of the processor 172, the I/O subsystem 176, and/or other components of the notification device 108.

The communication manager 250 is configured to manage communications of the notification device 108. In use, the communication manager 250 receives notifications from the telematics server 102. Additionally, in some embodiments as discussed in more detail below, the communication manger 250 may transmit user feedback to the telematics server 102. Such feedback may be based on the received notifications.

The alert manager 252 is configured to manage the notifications received from the telematics server 102. In embodiments in which the notification includes instructions, the alert manager 252 is configured to execute the instructions of the received notification. For example, in embodiments in which the notification includes information to be provided to the user, the alert manager 252 is configured to present the information to the user via the output device 178 (e.g., via a display screen or speaker). Additionally, in embodiments in which the notification includes instructions, the alert manager 252 may activate an alert device (e.g., a visual, tactile, or audible alert device) of the notification device 108 based on the notification.

Referring now to FIG. 3 , in use, the telematics device 104 may execute a method 400 for managing telematics data. It should be appreciated that, in some embodiments, the operations of the method 300 may be performed by one or more components of the environment 204 of the telematics device 104 as shown in FIG. 2 .

The method 300 begins with block 302, in which the telematics device 104 may perform various initializations procedures. For example, the telematics device 104 may load an operating system and/or various software or software extensions in block 302 as part of a power-up cycle. Subsequently, in block 304, the telematics device 104 receives telematics data. For example, in block 306, the telematics device 104 may receive the telematics data from one or more vehicle sensors 164. Additionally or alternatively, in block 308, the telematics device 104 may receive the telematics data from one or more vehicle controllers 162. Furthermore, in embodiments in which the telematics device 104 includes the local sensors 156, the telematics device 104 may receive telematics data from the local sensors 156 in block 310.

In block 312, the telematics device stores the received telematics data in the local database 240. In doing so, in some embodiments, the telematics device 104 may compact the telematics data in block 314. For example, the telematics device 104 may use a suitable compression algorithm or saving schema to reduce the overall size of the saved telematics data. Regardless, in block 316, the telematics device 104 transmits the newly received telematics data to the telematics server 102. In doing so and as discussed above, the telematics device 104 may be configured to transmit the telematics data as it is received from the sensors 164, controllers 162, and/or local sensors 156. Alternatively, in other embodiments in block 318, the telematics server 102 may be configured to transmit the telematics data based on a schedule set forth in the transmission ruleset 242 as discussed above.

Referring now to FIG. 4 , in use, the telematics server 102 may execute a method 400 for constructing the event model 222 to facilitate analyzing telematics data. It should be appreciated that, in some embodiments, the operations of the method 400 may be performed by one or more components of the environment 202 of the telematics server 102 as shown in FIG. 2 .

The method 400 begins with block 402, in which the telematics server 102 may perform various initializations procedures. For example, the telematics server 102 may load an operating system and/or various software or software extensions in block 402 as part of a power-up cycle. In some embodiments, in block 404, the telematics server 102 may retrieve, receive, or otherwise obtain a pre-trained event model 222. The pre-trained event model 222 may include a number of predefined or pre-established rules, including predefined temporal-based rules, predefined location-based rules, predefined historical-based rules, pre-defined sequential-based rules, predefined relational-based rules, and/or other rules and/or conditions. Such predefined rules may be manually defined in the pre-trained event model 222 or may be constructed during a training session using training telematics data. For example, the pre-trained event model 222 may define “global” rules that are applicable to a whole set or range of telematics devices 104 or otherwise considered universal.

After the telematics server 102 has performed the various initialization procedures in block 402, the telematics server 102 monitors for telematics data from the telematics device 104 in block 406. If telematics data is received in block 506, the method 400 advances to block 408 in which the telematics server 102 stores the received telematics data in the local telematics database 220.

Subsequently, in block 410, the model manager 214 of the telematics server 102 performs unsupervised learning on the received and stored telematics data using the machine learning engine 216. The learning is unsupervised in that the telematics data is unlabeled from the driver of the vehicle 106 or other user. In performing the unsupervised learning on the receive telematics data, the telematics server defines one or more rules of the event model 222. For example, in block 412, the telematics server 102 may define one or more temporal-based rules. Each temporal-based rule may define an expected temporal operational condition and/or characteristic of the vehicle 106. For example, a temporal-based rule may define an expected time period of operation of the vehicle 106, an expected time at which the vehicle 106 should be started or stopped, an expected time at which the vehicle 106 should be located at a particular location, an expected completion time of a trip, and/or other time-based operational conditions and/or characteristics. In block 414, the telematics server 102 may define one or more location-based rules. Each location-based rule may define an expected location-related operational condition and/or characteristic of the vehicle 106. For example, a locational-based rule may define a geofenced area of operation for the vehicle 106, an expected location of the vehicle 106, an expected route of the vehicle 106, and/or other location-based operational conditions and/or characteristics.

In block 416, the telematics server 102 may define one or more historical-based rules. Each historical-based rule may define an expected operational condition and/or characteristic of the vehicle 106 given the past telematics data. For example, a historical based rule may define an expected maintenance of the vehicle 106 based on a previous maintenance of the vehicle 106, an expected speed (or max speed) of the vehicle 106 based on a previous speed or location of the vehicle 106, and/or other historical-based operational conditions and/or characteristics. In block 418, the telematics server 102 may define one or more sequential-based rules. Each sequential-based rule may define an expected operational condition and/or characteristic of the vehicle 106 given an immediate past operational condition and/or characteristic of the vehicle 106. For example a sequential-based rule may define an expected location of the vehicle 106 based on the immediately prior location of the vehicle 106, an expected weight of the vehicle based on the immediately prior location of the vehicle 106, and/or other historical-based operational conditions and/or characteristics. In block 420, the telematics server 102 may manually define one or more relational-based rules. Each relational-based rule may define an expected operational condition and/or characteristic of the vehicle 106 given the existence of another operational condition and/or characteristic of the vehicle 106. For example, a relational-based rule may define an expected cargo of the vehicle 106 given a present location of the vehicle 106, an expected max speed of the vehicle 106 given a present location of the vehicle 106, an expected operation start time given the particular day of the week, and/or other relational-based operational conditions and/or characteristics. In some embodiments, a single rule of the event model 222 may be composed of multiple sub-rules. For example, a rule may include both a location-based rule and a temporal-based rule (e.g., a rule that defines an expected location at a particular time of the day). It should be appreciated, however, that the telematics server 102 may define additional or other rules during the unsupervised learning based on the observed data by identifying patterns and/or outliers in the received telematics data.

During or subsequent to the unsupervised learning of block 410, the telematics server 102 constructs or otherwise generates the event model 222 based on the various rules defined during such learning. In some embodiments, the telematics server 102 may also perform supervised training in which a user of the telematics server 102 may “label” the received telematics data to improve the creation of the initial set of event rules. Additionally, in embodiments in which a pre-trained event model 222 is used, the telematics server 102 may update the pre-trained model to construct or generate the final event model 222. Regardless, in block 426, the telematics server 102 subsequently saves the generated event model 222.

Referring now to FIG. 5 , in use, the telematics server 102 may execute a method 500 for providing notifications to the notifications device 108. It should be appreciated that, in some embodiments, the operations of the method 500 may be performed by one or more components of the environment 202 of the telematics server 102 as shown in FIG. 2 .

The method 500 begins with block 502, in which the telematics server 102 may perform various initializations procedures. For example, the telematics server 102 may load an operating system and/or various software or software extensions in block 502 as part of a power-up cycle. Subsequently, in block 504, the telematics server 102 monitors for telematics data from the telematics device 104. If telematics data is received in block 504, the method 500 advances to block 506 in which the telematics server 102 stores the received telematics data in the local telematics database 220.

Subsequently, in block 508, the telematics server determines whether an unexpected event has occurred based on the received telematics data and the event model 222. As discussed above, the event model 222 includes or defines a number of rules that define expected operational conditions and/or characteristics of the vehicle 106. If the received telematics data does not match the relevant event rule, the telematics server 102 determines that an unexpected event (e.g., unexpected telematics data) has occurred. As such, the telematics server 102 may compare the received telematics data to one or more rules of the event model 222. For example, the telematics server 102 may compare the received telematics data to one or more temporal-based rules in block 510, to one or more location-based rules in block 512, to one or more historical-based rules in block 514, to one or more sequential-based rules in block 516, to one or more relational-based rules in block 518, and/or to one or more additional rules.

In block 520, the telematics server 102 determines whether an unexpected event has been detected based on the analysis performed in block 508. If so, the method 500 advances to block 522 in which the telematics server 102 generates and transmits a notification to the notification device 108. As discussed above, the notification may be embodied as a simple alert notification and/or may provide instructions to the telematics device 104 for providing information to the driver of the vehicle 106.

If no unexpected event was detected in block 520 or after the notification has been transmitted in block 522, the method 500 advances to block 524. In block 524, the telematics server 102 determines whether to update the event model 222. In some embodiments, the telematics server 102 may update the event model 222 based on every received telematics data. In other embodiments, the telematics server 102 may be configured to periodically update the event model 222 or update the event model 222 after a particular amount of telematics data has been received. Additionally, if the user of the notification device 108 has provided feedback in response to a notification, the telematics server 102 may update the event model 222 based on such feedback so as to perform a type of supervised machine learning using the feedback as labeled data. Regardless, if the telematics server 102 determines to update the telematics data in block 524, the method 500 advances to block 526 in which the telematics server 102 updates the event model 222 based on the recently received telematics data and/or user feedback. For example, in the illustrative embodiment in block 528, the telematics server 102 updates the event model 222 based on the received telematics data and/or user feedback using the machine learning engine 216 (e.g., by using unsupervised or supervised learning, respectively). In doing so, the machine learning engine 216 may use any suitable machine learning algorithm to update the event model 222. In some embodiments, in block 530, the telematics server 102 may also transmit the updated event model 222 to the telematics device 104. In such embodiments, the telematics device 104 may utilize the updated event model 222 to perform some amount of local analysis of the telematics data as discussed above.

Referring now to FIG. 6 , in use, the notification device 108 may execute a method 600 for managing notifications received from the telematics server 102. As discussed above, the notification device 108 may be embodied as a separate computer device (e.g., a fleet manager server, a smartphone or mobile communication device, etc.) in some embodiments. In other embodiments, the notification device 108 may be incorporated into or otherwise embodied as the telematics device 104. In such embodiments, the telematics device 104 may execute the method 600. Regardless, it should be appreciated that the operations of the method 400 may be performed by one or more components of the environment 206 of the notification device 108 as shown in FIG. 2 .

The method 600 begins with block 602, in which the notification device 108 may perform various initializations procedures. For example, the notification device 108 may load an operating system and/or various software or software extensions in block 402 as part of a power-up cycle. Subsequently, in block 604, the notification device 108 monitors for notifications received from the telematics server 102. If a notification is received, the method 600 advances to block 606.

In block 606, the notification device 108 generates an alert based on the received notification. For example, in block 608, the notification device 108 may activate an output device 178 to alert the user of the notification device 108 about the notification. The particular output device 178 used may be determined based on the notification and/or information included therein. As such, the alert may be embodied as a simple audible, visual, or tactile alert in embodiments in which the notification is a simple alert notification. However, in other embodiments in which the notification includes information, the alert may be embodied as the presentation of such information to the user via a respective output device 178 (e.g., via a speaker or display). Additionally or alternatively, in some embodiments, the notification device 108 may transmit the alert to other devices. For example, in embodiments in which the notification device 108 is located within the vehicle 106 or otherwise associated with the vehicle 106, the notification device 108 may be configured to transmit the alert to the telematics device 104, which may in turn generate the alert via one of the output devices 152.

Subsequently, in block 612, the notification device 108 determines whether to obtain user feedback regarding the received notification. For example, in some embodiments, the notification device 108 may request user feedback for each notification or request feedback only in response to particular criteria (e.g., the number of notifications received within a reference time frame). Additionally or alternatively, the user may manually provide feedback as desired. Regardless, it should be appreciated that the user feedback embodies a type of labeling of the notification, which may be used by the telematics server 102 to update the event model 222 using a supervised machine learning algorithm as discussed above.

If the notification device 108 determines to obtain user feedback in block 612, the method 600 advances to block 614 in which the notification device 108 prompts the user for feedback on the recently received notification. The notification device 108 subsequently receives the user feedback in block 616 and transmits the feedback to the telematics server 102 in block 618. The method 600 subsequently loops back to block 604 in which the notification device 108 continues to monitor for notifications from the telematics server 102.

Referring now to FIG. 7 , in embodiments in which the telematics device 104 is configured to perform the local analysis of the telematics data and includes the local event model 238, the telematics device 104 may execute a method 700 for managing telematics data. It should be appreciated that, in some embodiments, the operations of the method 700 may be performed by one or more components of the environment 204 of the telematics device 104 as shown in FIG. 2 .

The method 700 begins with block 702, in which the telematics device 104 determines whether an update to the local event model 238 is available from the telematics server 102. If so, the method 700 advances to block 704 in which the telematics device 104 receives the updated event model 238 from the telematics server 104. Subsequently, in block 706, the telematics device 104 receives telematics data. For example, in block 708, the telematics device 104 may receive the telematics data from one or more vehicle sensors 164. Additionally or alternatively, in block 710, the telematics device 104 may receive the telematics data from one or more vehicle controllers 162. Additionally, in embodiments in which the telematics device 104 includes the local sensors 156, the telematics device 104 may receive telematics data from the local sensors 156 in block 712.

In block 714, the telematics device stores the received telematics data in the local database 240. In doing so, in some embodiments, the telematics device 104 may compact the telematics data in block 716 as discussed above. Subsequently, in block 718, the telematics device 104 transmits the newly received telematics data to the telematics server 102. In doing so and as discussed above, the telematics device 104 may be configured to transmit the telematics data as it is received from the sensors 164, controllers 162, and/or local sensors 156. Alternatively, in other embodiments in block 720, the telematics server 102 may be configured to transmit the telematics data based on a schedule set forth in the transmission ruleset 242 as discussed above.

Subsequently, in block 622, the telematics device 104 determines whether an unexpected event has occurred based on an analysis of the received telematics data and the local event model 238. To do so, the telematics device 104 may compare the received telematics data to one or more rules of the local event model 238 using a methodology similar to the telematics server 102 described above in regard to block 508 of method 500.

In block 724, the telematics device 104 determines whether an unexpected event has been detected based on the analysis performed in block 722. If so, the method 700 advances to block 726 in which the telematics device 104 generates an alert to the driver of the vehicle 106. As discussed above, the alert may be embodied as a simple alert notification and/or may provide information to the driver of the vehicle 106. Additionally, in some embodiments in block 728, the telematics device 104 may receive feedback from the driver of the vehicle 106 based on the generated alert and update the local event model 238 based on the feedback using a supervised machine learning algorithm as discussed above. Regardless, the method 700 subsequently loops back to block 702 in which the telematics device 104 continues to monitor for an updated event ruleset from the telematics server 102.
